Smoker's life expectancy

If a nation wide ban on outdoor smoking did come into effect, life expectancy would probably go up. Most would think that that is a good thing. I believe that it may not be a good thing. The older Americans live, the more populated the U.S. would become. Prices would go up because of demand and America would see a more expensive future. Also, I believe that America would be an even fatter nation due to people quitting smoking because of the bans. Smoking addiction and food addiction have a lot in common. It is a psychological behavior where one feels the need to involve the movement of hand to mouth. This behavior usually comes into effect when relaxed or bored. You may hear people say they smoke because it is something to do and you may hear the same from people who over-eat.
